Let me share with you the license agreement that NXP has for all his documentation, basically, you can use the documentation, quoting NXP and it is only if you are using and NXP product.
Just to confirm, what I understand is that I can copy part of the documentation as inline documentation for the Motorolla 68000 asm editor, as long as I quote that NXP is the owner of the documentation/Motorolla 68000 copyright.
